AN intoxicated out-of-work chef had no absolutely no recollection of disgracing himself by falling asleep at a busy Brisbane bus stop without any pants on, a court has been told.

The Brisbane Magistrates Court was told Michael Rolf Bruan, 29, was arrested after members of the public reported seeing a man - naked below the waist - running across a busy Brisbane St about 5.30pm on March 24.

Prosecutor Sharon Carruthers said when police arrived they found Bruan passed out on a bus bench, with no pants on and his genitalia exposed.

Sergeant Carruthers said the incident happened at one of the city's most regularly used bus stops at one of the busiest times of the day - meaning Bruan had exposed himself to countless unsuspecting commuters.

The court was told numerous people had told Bruan to pull up his pants - which were down around his ankles - but that he refused to do so.

Solicitor Ed Whitton, for Bruan, said his client had no recollection of having his pants down and was mortified when later told about the behaviour.

The claim prompted magistrate Stuart Shearer to say: "When he was aroused (from his sleep) he must have noticed his pants weren't up."

"I have trouble accepting ... that (Bruan) didn't know (his) pants were down and (his) genitalia was exposed.

"Nobody needs to see, or wants to see anyone's genitalia on the street."

The court was told Bruan was also arrested for stealing a boy's school bag containing about $200 worth of "mystical-style" collectors cards.

Bruan was fined $500 after pleading guilty on Saturday to charges of stealing, public nuisance and a breach of bail.
